Subject [jira] [Commented] (HADOOP-8315) Support SASL-authenticated ZooKeeper in ActiveStandbyElector
Date Wed, 25 Apr 2012 23:30:18 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262238#comment-13262238

Todd Lipcon commented on HADOOP-8315:
-------------------------------------

bq. Todd afaik this is not the case, you just need to wait until you see SaslAuthenticated

How do we know if we need to wait, though? Some users might not be using sasl auth, in which
case we don't need to wait for SaslAuthenticated.. but if we wait for it, then it may never
come, right?

> Currently, if you try to use SASL-authenticated ZK with the ActiveStandbyElector, you
run into a couple issues:
> 1) We hit ZOOKEEPER-1437 - we need to wait until we see SaslAuthenticated before we can
make any requests
> 2) We currently throw a fatalError when we see the SaslAuthenticated callback on the
connection watcher
> We need to wait for ZK-1437 upstream, and then upgrade to the fixed version for #1. For
#2 we just need to add a case there and ignore it.
